to an improved fluid valve for containers such as bladders oi rubber or the like playing balls, gas balloons,

bottles, gas masks,

material, pneumatic tyres, air cushions, water life beltsA or containers of glass, metal or the like of the type in which a rubber tube can be folded on itself to preventv escape oi huid through it According to the present invention, the valve comprises a rubber tube mounted on a casing and having a vvariation in cross-section at a point between the inlet opening tube and the outlet from the or openings to the tube to the interior of the casing, which, variation in cross-section automatically predetermines the point of folding voi the tube on itself, to

the tube.

Britain January 4, 1934 thereto, and in this case, the sleeve 3 is connected by a fold 4 to an outer sleeve 5 having a ange 6 for vulcanzing to the bladder `or cushion 2. This outersleeve 5 has a lug or spigot 1 upon it, to which the cuter end 8 of an extension tube' 9 of'rubb'er is secured, theopposite end III of which tube is integral with, or connected to the tube I.

The' extension tube 9 preferably has a change in cross-section at a point II formed preferably 1o by grooving the tube 9 at this place. Alternatively, this change in cross-section may be formed by strengthening the tube at two adjacent points.

By the former means a recessed seating is prolvided on one-half-wall of the tube for the folded part of the other half-wall.

Holes I2 are provided between the pointsot change in cross-section as at II and I3 and the connection point 1, so that after'inilation of the ball, cushion or the like with the parts in the 20 position shown in can be pushed into the position shown in Figures 3 and 4, in which the tube 9 folds upon itself to provide a pressure tight vseal orvalve at the fold II.

If desired, the extension tube 9 may also have a change in cross-section, such as for instance, by weakening thel tube as at I3, between the openings I2 'and the connection with the part 1, so that a second hinge line is formed, when the '-parts are in the -position shown inFigures 1 and inilation or deflation of the ball,

part of a container it may be formed, integral with a conical plug as at I5 (Figure '6) so that it c an be inserted in the orice of a bottle, jar or other container.

' In the construction of Figure 7, the valve consists of a tube I1, of rubber mounted by means ol' a diaphragm I8, upon a ring I9, whichin certain cases, can of course be integral with the casing. In the case shown, the ring I9 has grooves in it, viz, an internal groove to receive a rigid ring 20 of rubber and an external groove to receive a beading 2I on the neck of the hot water bottle 22, this beading 2| being securely clamped within thegroove in the ring I9 by means of a metal ring 23 slipped over the open end 24 of the hot water bottle by tensioning this.

The tube I1 has an extension piece 25 connected to a pipe 26 on the ring I9, and is weakened to form a fold line as at 21, openings 28 being provided between this fold-line and the connection 26 to the ring I9.

Additional openings 29 are provided on the op'- posite side of the diaphragm to that on which the' valve I1 is disposed, so that when the parts are in the position of Figure 8, liquid lled inthe open end of the neck 24 enters when the openings 29' pass down the stem of the valve I1, and out into the bottle through the openings 28.

To facilitate lling, an air tube 30 may be provided, Which, when the valve is closed by pushing in the stem 3l, bends or folds upon itself to seal this.

In the modified arrangement shown in Figures 9 and 10, the stem for withdrawing the valve or pushingvit into the closed position is formed as a rubber tube 32, sealed bya plug 33, which receives the open end 34 of the air tube 35.

In a further modiiied form of construction shown in Figures 11 and 12, the valve is disposed outside the container and consists of a stem 36 having openings 31, and fold-line 38 between the holes 31, and the connection of the valve to the body of the'container 39. As shown in Fig. 11, liquid may be filled into the container through the holes 31, whereupon the valve can be folded down upon itself upon the hinge line 38 to seal the valve. If desired, a second fold-line 40 may I declare that what I claim isz- 1. A fluid valve .for containers comprising in combination a ange, a flexible rubber tube having its outer wall flexibly connected to said ange for permitting relative movement` thereof, said tube having outlet holes and having a variation in its cross section between the open en d of said tube and said holes, said variation in cross-section causing Ythe tube to be folded thereat to hermeticaliy seal the tube.

2. A uid valve for containers comprising a flange, a rubber tube having an open end and openings intermediate its length and a variation in cross section between said openings and the open end, and a second variation in cross section between the openings'and the inner end of the tube, means to secure rigidly the inner end of the tube to the container, and a flexible diaphragmv connecting the outer wall of the tube and said 3: A fluid valve for containers comprising in combination, a tube sealed tothe container and providing a passage therethrough for the movement of huid, said tube having a exible portion for permitting a folding of the tube and for permitting movement thereof relative to the container, said tube having the inner end thereof connected to the container and having a variation in cross-section in the flexible portion thereof, said variation and the connection of the inner end of the tube to the container cooperating so as to localize the folding of the tube at the point of variation in cross-section thereby effecting a sealing of the passage inthe exible portion when the outer end of the tube is forced inwardly relative to the container.

4. A duid valve for containers comprising in combination, a tube having a iiexible portion permitting a limited longitudinal movement of said tube, flexible connecting means intermediate the vends of said tube for connecting the tube to the container and for sealing the container, the inner end of said tube being anchored within the container and disposed so as to cause in the exible portion of the tube below said flexible connecting means a fold which is shifted longitudinally of the flexible portion of the tube upon longitudinal movement of the tube, said tube having an opening inside of said flexible connecting means and a variation in cross-section between said opening and said flexible connecting means, the construction being such that, when the tube is longitudinally extended for iniiating the container, the

fold in the tube is located inwardly of said opening and when the tube is retracted, the fold occurs at the variation in cross-section and outwardly of the opening thereby sealing the tube and the/container. y i

5. A uid valve for containers comprising in combination, a tube flexibly sealed to the container and providing a passage therethrough for the movement of iiuid, said tube having a flexible portion for permitting longitudinal movement thereof relative to the container, said tube having the inner end thereof connected to the container and disposed so as to eifect a folding of the tube in said flexible portion, said tube having an opening through the flexible portion thereof and a Variation in cross-section between said opening and the open end of the tube, said variation in crosssection-and the connection of the inner end of the tube to the container cooperating to localize the folding of 'the tube at the point of variation in cross-section thereby effecting the sealing of the A passage inthe flexible portion when the outer end of the tube. is forced inwardly relative to the container, said tube having a second variation in cross-section in the iiexible portion thereoi between said opening and the inner end of the tube,

said second variation in cross-section cooperatingwith the connection of the inner end of the tube to the container to localize the folding of the tube at the said second point of variation Whenthe tube is moved outwardly relative to the container tainer and disposed so as to cause in the flexible portion' of the tube below said dexible connecting means a told which is shifted longitudinally of cura at the variation in cross-section and outthe exible portion oi. the tube upon longitudinal vwardiy o! the opening thereby sealing the tube. movement of the tube, said tube having an open- 'a 'exibie air conduit communicating with the ining inside of said exible connecting means .and terior of the container and having the outer end a variation imcross-section` between -said openinz thereof connected to said tube to facilitate the 5 and said flexible connecting means, the construciiing of the container with a liquidysaid air con- E.tion being such that, when the tube is longitudiduit being movable with said tube and being naliy extended for iniiating the container, the sealed when said tube is retracted in its closed fold inthe tube is located inwardly or said openposition.
